(Cl. 164-93) In presses or machines as heretoforevmade, it the shoe upper Otherwise all ready fOr' assembling lo out press. particularly intended for work on shoes, a closed upper, upon the quarter sections, through intended for ladies Wear, it has been customary to be presented, while held flat and preferably cut out portion to any other portion of the upmachine is in this provision ot protecting spaces work portion during lasting. Then after the formed, to be quickly, accurately and removably shoe was otherwise completed, it was necessary to presented to the cutting devices. Furthermore,

My present invention is intended to obviate This feature is of great importance, and being the diiiiculties above noted in manufacturing distinctly new, I claim the same broadly herein. openwork shoes, and enables these shoes to be A further important feature consists in the made by a new process, as explained in the patprovision oi' a machine and operating instru- The machine of my present invention is diviously marking or forming any pattern on the 5o rented to perform the cutting out operations for Work. This desirable result I accomplish by the openwork shoes, following any design desired, as provision of -work cutting and work holding insuring the cutting out action with exact uniformity upon successive uppers of similar design. This feature is most important in practice, as the cutting out action leaves a plurality of narrow strips or straps and the spacing or widtl` o these straps is most important. By means of my invention, wherein the straps are formed with exact relation to the edge or predetermined portion of the shoe upper, suol. as the top seam, side stitching or other fixed portion in the design, the resulting openwork is formed accurately with all straps, widths and strips of proper width, and with opposite quarter sections, for example, in perfect cooperation. This is an important advantage resulting from cutting out the openwork portions after the shoe upper sections have been stitched and united, as distinguished from first cutting out the upper sections and then stitching and uniting same.

An additional feature in the present machine is that I have devised, invented and developed a novel type oi combined anvil and cutting dehave termed a cutting anvil. In a machine of this type, it will be appreciated that it is necessary to have a capacity for constant change, variations and differences in design of the cut out portion, particularly when shoe uppers are being operated upon. Therefore, it is essential that interchangeable cutting devices be provided and I have devised in connection with the cutting devices an anvil on which the material is cut and permitting a ready interchange of designs and devices. Also it is desirable and in many instances it is essential that the material be held or clamped in xed predetermined posi tion, and therefore I have combined, in my cutting anvil, the cutting devices, an anvil-like member on which the work is held, together with clamping means, all constituting a complete selicontained unit, viz, my cutting anvil, which unit, furthermore, is interchangeable with others for operation in the same machine. Therefore my present invention includes means capable of instantly changing the machine from cutting one design or pattern, to an entirely different design or pattern, by the same interchangeability and adjustability of cutting anvils. Each cutting anvil has preferably, both the cutting devices for forming the cut out or openwork portions, together with a cooperating clamping member, adapted to hold the work rrnly in position for the cutting out operation.

A still further feature and one of great importance, consists in the fact that I utilize the clamping means either alone or as a combined clamp or holder for the work, and preferably as a guiding, or gauging, or alining device, to insure that the cutting means and work will register. This enables me to eliminate entirely any marking or previously stencilllng a design on the upper, before it is cut, as I can rely entirely upon the combined gauging and holding or clamping member to adjust the work relatively therewith. and the resulting cutting out operation insures perfect registering and alining of the design cut out, as, ior example, with the fixed edges of a shoe upper. This feature in practice gives the important advantage of enabling the operator to speed up work on this machine, to quickly and accurately aline the work with regard to the clamp, because the latter is outside and on top of the work, While the cutting devices are underneath and out oi sight. The operator need only position the cork with regard to the topmost portion of the cutting anvil, viz, the clamp, and

then at once position the same under a moving part such as a plunger and the tripping of a treadle will complete the cutting out action.

The clamping device as above noted constitutes also a protecting guard for that portion of the work adjacent the cutting out devices, during the cutting operation, and furthermore I form this clamp as a complete guard partly or entirely around the cut-out portion. Thus I hold the part of the work to be cut out, not merely at one or two points, but partly or entirely around the openwork portion to be formed, the clamp being cut out proportionately or in cooperation with the design of the openwork and protecting, as well as holding the material being operated upon. This clamp is preferably made of thin sheet metal, and preferably also is hinged or otherwise removably attached to the cutting anvil as above explained, and is so constructed and arranged as to place the work under proper tension to prevent displacement of same during the cutting out operation. My improved clamp, which I have designated as a mask, is of great importance in the operation of cutting out, perforating, or ornamenting parts or portions of material. Heretoiore great difficulty has been experienced in operating upon such articles as Vamps, toe tips, or the like, in flat bed cutting machines, as the material would wrinkle. would not lie evenly, and no prior clamping or holding devices of which I am aware, extended closely adjacent the line of pressure of such prior machines, except only at the immediate front of the machine. My invention of a holding, protecting, and also gauging mask, performs the very important and vital function of clamping the material to be operated upon, sufficiently along the side or sides oi the cutting or ornamenting action and preferably partly or even entirely around the portion to be operated upon. Therefore, by extending my mask or clamping action beyond the former line oi holding and partly surrounding the cut out or ornamented portion, I have eliminated prior difilculties, and am thus enabled to operate upon ilat bed work much more advantageously than was formerly possible. In addition to this feature, my mask. clamp or guard in any form and in combination with protecting spaces. recessesor clearance. as herein explained. is new. and is claimed broadly herein. This clamp also, being of thin sheet metal. when adapted to press down upon a completed shoe upper, can easily have extra portions cut out. for any purpose as at the tip seam or other place where there is an extra mass or thickness of material, and thereby prevent damage to the same. eliminate breaking of stitching. marrlng of patent leather. tearing strain on satin, suede or other material oi' which the upper is made.

Positioned and arranged under the protecting guard or mask I provide a yieldable element, cnoperating with the portion of the material adjacent the sections to be cut out. to yield with the pressure or the plunger during the cutting out action, and acting as a "stripper element. during the release oi the pressure and to lift and restore the uncut part of the work above the cutting dies. This stripper element may be any yieldable member, such as a steel plate mounted on a plurality of springs and having a form or contour substantially corresponding to the design of the cut-out die and resulting cut-out. portions on the work. While l preferably utilize a metallic yielding strip, anv yivldinc .llmmi such as rubber or the like can this yielding In addition openwork portions of a I accomplish this by having the supporting means or cutting anvils so positioned and arranged relatively with the line of pressure of the cutting operation; and the anvil, that the supporting only partly into the paper backing. and also because of the peculiar configuration and dimculty of supporting many of the cut out dies. especially when in curved or intricate designs. In order to or distortion of the dies, and

each pair of shoes.i same design, the dies must be rigidly supported and directly under the line of pressure during the cutting out operation. To insure the accurate cutting out operation. and to carry out the "balanced position as above explained, while also affording the clearance desirable for permitting this machine cutting operation, I support the die on a firm, rigid anvil or other equivalent work support, so that the line of pressure will be rigidly resisted and all springing" and distortion 'of the dies prevented. In the particular form of die and supporting member, anvil or slide which I utilize in the present case, and wherein one portion of the die holder projects or overhangs same, to facilitate the fitting of a closed upper therearound, I provide a cooperating supporting post so that the die will be rigidly positioned. and the pressure from the plunger irmly resisted, thereby insuring the smooth and for any design. and insures a uniform and satisfactory operation of the machine.

An additional feature in the machine of my shown in the accomthe cutting anvil itself during the last portion of its positioning action, to thereby operate through mechanical levers or age or damage.

Referring to the drawings, l0 designates a base a sectional elevation of a fragment having formed integral therewith and extending upwardly therefrom abody II of a machine, which machine is adapted to rest on a bench or other support, and rotatably mounted in bearings I2 formed in the body II and adjacent to the top thereof is a power shaft I3. Keyed to the shaft I3 intermediate the ends of such shaft and between the bearings I2 is an eccentric I4 on which is rotatably mounted an eccentric ring I5 that is. in turn, adjustably mounted for rotation in an eccentri` strap I5, this eccentric strap being split at one end and this end being provided with laterally extending lugs I1. One of these lugs I1 is drilled as a clearance hole for the body of a bolt I3 while the other of the lugs I1 is drilled to receive the threaded end of such bolt I8 and this bolt I9 is utilized, in connection with the lug I'I, as a means for drawing the split end of the eccentric strap together in order to clamp the eccentric ring I5 therein. This eccentric strap I6 is formed integral with one end of a connecting rod I9, the other end of this connecting rod being pivotally attached to a shaft 2li secured in the lower end of a crosshead 2|. This crosshead 2l is slidably mounted for vertical movement in guideways formed on the machine by means of straps 22, these straps being secured to the machine by bolts 23. The plunger 2I is provided on its lower end with a removable face 24. Formed integral with the body III and extending forwardly therefrom is a table or platen 25, which platen is provided on its upper face and on either with guideways 26 for a purpose to be hereinafter described. The platen 25 lies in the path of movement of the vertically movable plunger 2 I.

Rotatably mounted on the main shaft I3 and at one end thereof is a driving pulley 21, power being furnished from any suitable source to such The inner face of the driving pulley 21 is counterbored and secured to the bottom of such counterbored portion is a member provided on the face thereof adjacent the opening of the counterbored portion with two radially arranged sectors 29, as shown in Fig. '7. Secured to the shaft I3 is a member 30 provided with a longitudinally arranged slot 3|. Slidably mounted in the slot a spring 33 being arranged between the end of the slot 3l and such plate 32, which spring tends to force the plate 32 to the right, as viewed in Fig. 4 or into such a position as to engage with one or the other of the sectors 29. The plate 32 is provided on its outer edge with a V-shaped slot 9 in which is adapted to nt a wedge-shaped member 34. In the position shown in Fig. 4 with the wedgeshaped member 34 in the slot 9, the plate 32 is held to the left against the tension of the spring 33 and with its outer end out of engagement with the wedge-shaped sectors 29. Under these circumstances, the pulley 21 will be freely rotatable c-n the shaft I3 and the shaft I3 will remain stationary. If the wedge-shaped member 34 is withdrawn from the V-shaped slot 9, the spring 33 will force the plate 32 to the right. as viewed in Fig. 4, and such plate will be engaged by one or the other of the wedge-shaped sectors 29, thus locking the pulley 21 and the shaft I3 together and this condition will prevail until the Wedgeshaped member 34 is replaced in its original position to engage in the wedge-shaped slot 9. The wedge-shaped member 34 is secured to the upper end of an arm 35 rotatably mounted on a shaft 36 secured in a member 31 attached to 38. The member 31 is provided with a projection 39 which extends upwardly toward the pulley 21 and secured to the end of this projection is one end of a spring 40, which spring is coiled around the hub 4I of the arm 35and extends upwardly, its upper end entering a perforation near the upper end of the arm 35, as clearly shown in Figs. 4 and '1. This spring 49 is arranged to cause a rotative movement of the arm 35 about the shaft 35 in a clockwise direction, as viewed in Fig. '1, so that, normally, such arm 35 will maintain the plate 32 in its left hand position as viewed in Fig. 4 against the tension of the spring 30 and therefore the pulley 21 is free to rotate on the shaft I3. Secured to the front edge of the arm 35 in any suitable manner is a plate 42. Engaging such plate is an adjusting screw or bolt 43 that is threaded through a lug 44 formed integral with the body member I I such adjusting screw or bolt 43 being utilized to adjust the inward or right hand movement of the arm 35 about the shaft 36. Rotatably mounted on the shaft 35 is a member 45. Pivotally mounted on said member 45 is the upper end of a treadle rod 46 which extends downwardly to a point adjacent the floor and is provided with an ope. ting treadle (not shown) for the convenience of the operator. Formed on the member 45 at its upper end are lugs or ears 41 in which is pivotally mounted on a pin 49 the latch member 49. The member 45 is drilled at 50 to receive a coil spring 5I, the upper the body II by bolts free end of this spring engaging with the rearwardly projecting end of the latch member 49 and tending to rotate such member 49 in a clockwise direction, as viewed in Fig. '1. The end of the latch member 49 remote from the pin 43 is provided with a hook end 52 which engages with the member 42. It is obvious, from an inspection of Fig. 7, that if the treadle rod 46 is pulled downwardly in the direction of the arrows shown, the hook 52 engaging with the plate 42 on the arm 35 will move the upper end of such arm 35 in an anti-clockwise direction and thus tend to pull the wedge-shaped member 34 out from the V-shaped slot 9 in the plate 32, thereby allowing such plate 32 to be moved to the right, as viewed in Fig. 4, under the inuence of the spring 33. The under face or edge of the latch member 49 is cut away at 53 to form a cam. Formed integral with the body member I I and extending outward therefrom is a lug 54 through which is threaded a bolt 55 and the upper end of such bolt 35 engages with the cam surface 53, as clearly shown in Fig. "I The cam surface 53 is so arranged relative to the screw 55 that, as the latch member 49 moves to the left, as shown in Fig. '7 when the treadle rod 46 is moved downwardly in the direction of the arrow, the hook end 52 will move upwardly about the pin 4B as a center thereby releasing the plate 42 after the wedge-shaped member 34 has been moved from the V -shaped slot 9 in the plate 32. Under these circumstances, it will be apparent that. once the wedge-shaped member 34 has been removed from the V-shaped slot 9, the spring 33 will force the plate 32 to the right and into the path of movement of the wedge-shaped sectors 29 and the spring 4I! will move the upper end of the arm 35, and therefore the wedge-shaped member 34, into position whereby the wedge-shaped member 34 will be ready to force itself into the V-Shaped slot 9 when the plate 32 has completed one revolution. The above construction, therefore, Vprovides a means for positively allowing but a single revolu- `shaft 62 and with relation tion of the shaft I 8 by power transmitted from the pulley 21.

62 rotatably mounted in the body member ll, a spring 63 secured at one end to the arm 6I viewed in Fig. 7, and forcing the plate 51 upward and into position between the members 56 and 39. Secured to the shaft 62 intermediate the ends thereof is an arm 55, which arm lies above the platen 25, as clearly shown in Fig. 2. Arranged for sliding movement in the guideways 26 on the top of the platen 25 is a base 66 which has secured thereon and at its upper end a cutting anvil 61, the details of which will be later described. As best shown in Figs. 1 and 2, the proa substantial working space for the hands of the operator above the platen 25 and below the plunger face 24 of the machine and at the sides of the Work Supporting and cutting device to facilitate adjusting and holding of the work without danger of injury to the operators hands. Adjustably secured to the top of the platen by Wing screw |68 is an anvil rest 68, which anvil rest acts as a support for the relatively unsupported end of the cutting anvil 61. Secured to the frame of the machine by screws 268 is a stop plate 26| which lies in the path of movement of the cutting anvil 61 and Ain such relation thereto that to the rear end of the cutting anvil 61 that when the anvil 61 is moved to its most rearward position with the base 66 in engagement with the anvil 61, the rear end of such cutting anvil 61 will engage with the arm 65, rotating the shaft 62 and causing the cam surface 6U to engage with the end of one arm of the bell crank lever 58, rotating such bell crank lever in an anti-clockwise direction, as viewed in Fig, 7, and moving the attached plate 51 downward from between the members 56 and 38. At this instant the end of the cutting anvil 61 comes into engagement with the stop plate 20L When this point is reached, and only when this point is reached, will it be possible for the operator, by pressing on the treadle (not shown), to pull the treadle rod 46 downward and move .the wedge-shaped member 34 out from between the the shock imparted toit by the plunger 2|.

projection 33 and the hub 28. 0i'. course, as the member 45 is rotated about the shaft 88, the hook end 52 of the latch member I8 will be released from the arm 35 and the spring 40 will tend to move the arm 35 back into its initial position. With this device, therefore, positive safety `is assured in that it is imposible to operate the clutch mechanism until the work holding devices are correctly positioned beneath the plunger 2l and also itis impossible for the operator to allow the shaft I3 to continuously rotate.

Referring now to Figs. 11-17 inclusive wherein are shown the cutting anvil the die structure 15. Hingedly secured to the rear end of ithe cutting anvil 61 by hinge 18 is a mask 18. In this mask 19 is cut an opening 88 of such shape as to allow an upper 8| to be accurately positioned on the cutting anvil 61 with respect to the die 15 secured to such anvil. To facilitate the correct positioning of the upper on the cutting anvil 61, the contour of the opening 80, or certain portions of such contour, correspond in size and position, relative to the cutting die 15, with a seam or other xed portion of the upper 8l. With this arrangement, it is possible to correctly position an upper on the cutting anvil and in proper registry With the cutting die 15, even though it is impossible, under the circumby the upper. longitudinal section, as shown in Fig. 13; that is, the left hand portion adjacent the hinge member 18 is engaged by the portions 82 and 83 of the mask. Such portions will hold one end oi' the upper 8l in approximate position and the complete position of the upper will then take place, after which the operator will pull down the mask 19 into the position shown in Fig. 13 where it will be observed that the front portion of the upper is engaged by the portions 84 and 85. I have described the base 66 as being slidable in the guideways 26 and have shown such a base with the cutting anvil thereon so arranged in the guide ways 26 as to have the end oi' the cutting anvil 61 carrying the hinge 18 come into engagement with the member 65 secured to the shaft 82. It is obvious, therefore, that I may reverse the position of such base 66 in the guldeways 26. It will be noted from an inspection of Figs. 2 and 3 that the end of the cutting anvil 61 carrying the hinge 16 rests on top of the stop 68, this for the reason that such stop 68 acts as a support for the free end of such cutting anvil 61 and insures that the cutting anvil 61 will be held perfectly rigid against When the base 86 is reversed in the guides 26, as shown The mask 19 ls of the shape, in

in Fig. 10, the stop 68 can no longer support the free end of the cutting anvil 61. I have, therefore, on the base 66 pivotally mounted on shaft 66 a stop or support 91 which may be swung into position, as shown in dotted lines, so that, regardless of the manner of positioning the cutting anvil 61 on the platen 25. it will be rmly supported throughout its entire length and width against any shock imparted to it by the plunger 2 I.

One of the important features of my invention is the provision of means for utilizing a single continuous strip of paper ofindeterminate length between the plunger and the cutting die and utilizing practically every portion of such paper. Heretofore in operating cutting dies for cutting out designs on leather and the like, it has been usual and necessary to use a relatively long strip o paper for each cutting operation performed, and as but a very small portion of such strip of paper was used, the waste was considerable. My present device obviates the objections to prior structures and enables me to utilize every available portion of paper in a strip of indeterminate length. Secured to the body member |I and atone side thereof by bolts 99 is a member 99. Pivotally attached to the rear end of the member 89 on bolt |99 is the lower end of a standard 99. The member 69 is provided with a portion |46 above the pivot bolt |99 and this portion |46 is provided with an arcuate slot |41 through which passes a bolt |46 that screws into the standard 99. By means of the arcuate bolt |49 the standard 99 is ment about the bolt end of this standard 99 is secured a shaft 92, which shaft lies parallel with the driving shaft I3. On the shaft 92 is adapted to be placed a roll of paper the shaft and on each side of the roll of paper brackets 94, such brackets being adiustably secured to the shaft 92 by screws 95. Secured to the front of the body member II and at the top end thereof is a curved guide plate 96 provided at either side thereof with adjustable guide plates 91 for guiding the edges of the paper 96 fed from the roll 93. The front of the body member II below the curved guide plate 96 and on either side of such body member is provided with forwardly extending lugs or ears 99 and to each of such ears 99 is pivotally attached the lower end of a bearing arm |99. Screwed into the front or the body member II and extending through a perforation in each of the bearing arms |99 is a thumb screw I9| and located between the head of such thumb screw I9I and the associated bearing arm |99 is a coil spring |92 which tends to force the bearing arms |99 about their pivot point as a center in an anti-clockwise direction. Rotatably mounted at the upper end of the bearing arm |99 is a shaft |93 on which is secured a roller |94, which roller bears against the paper 99 as it passes over and around the curved guide plate 96. Secured to the lower end of each of the guide plates 22 and extending forwardly outward therefrom, as shown in Fig. l, are studs or rods |95. Numeral |96 designates a curved guide plate over which the paper 99 passes, and secured to the rear face of such guide plate in any suitable manner are lugs |91 spaced apart from each other and drilled to each receive one of the studs or rods |95, acting thereby as a means for positioning the curved guide plate |96 on the machine. The lugs |91 are drilled and tapped to receive the thumb screws |99 and by means of which the curved guide plate |96 may be adjustably mounted on the studs or rods |99. The upper portion of the curved guide plate |96 is provided with a pair of slots |99 in alinement with each other, as clearly shown in Fig. 4, and passing through such slots are studs I9 that are threaded at their outer end to receive a thumb nut III. rIhe studs |I9 and thumb nuts III act as means for securely and adjustably positioning on the outer end or face of the curved guide plate |96 the edge of the guides ||2 arranged one on either side of the strip of paper 99.

Rotatabiy mounted in suitable bearings in the body member I and lying parallel to the shaft 92 or the drive shaft I3 is a shaft |I3 on which is securely mounted a corrugated roller II4. rli'he shaft I|3 extends outward beyond the side of the body member II and has secured adjacent its extreme outer end a ratchet wheel II5. Rotatably mounted on the shaft II3 is a bracket |I6 provided with a longitudinal slot |I1 in which is adjustably mounted by bolt and nut I I8 and I I9 respectively the lower end of a connecting rod |29. Pivotally mounted in the bracket I I6 on paralleily arranged spaced shafts |2| are ratchets |22, springs |23 associated one spring with each of the ratchets |22 forcing such ratchets into engagement with the ratchet wheel II5. It will be obvious, from an inspection, for example. of Fig. 6, that an oscillatory movement of the bracket |I6 will cause an intermittent or step by step movement of the ratchet wheel II6, and therefore the shaft II3, in the direction of the arrow Secured to the shaft I3 rea face plate |24 provided with a radial slot |25 in which is adjustably mounted by means of bolt |26 and nut |21 the-upper end of the connecting rod |29. The radial slots II1 and |25 make it possible to alter the extent of oscillatory movement of the bracket ||6 imparted to it by the intermittent rotary movement of the shaft I3. Pivotally mounted on the body member II on each side of said member and above the corrugated wheel II4 are arms |26 and rotatably mounted on suoli arms in suitable bearings formed therein is a shaft |21, such shaft lying above, and parallel to, the shaft H3. Secured to the shaft |21 is a corrugated feed roll |29 which cooperates with the corrugated feed roll I |4 above described. Each of the arms |26 is provided adjacent its free end with an elongated vertical slot |29 through each of which passes a stud |39 that screws into the body member II, as clearly shown in Fig. 9. Between the under face of the head of the stud |39 and the upper surface of the arm |26 is arranged a coil spring |3| which exerts a downward tension on the arm |26 and tends to hold the corrugated roller |26 in engagement with the corrugated roller II4. The paper 99 is fed between the corrugated rolls ||4 and |26, an intermittent rotary motion being imparted to the corrugated roll I |4 by the oscillatory movement of the arm II6, and the paper 9B will be fed rearwardly of the Secured between the body member and the bearing arms |26 and located above, and extending transversely of, the paper 99 is a guide rod |32. The paper passes under such guide rod |32 and is led rearwardly of the machine. The portion of the rod |32 directly engaged by the body member II and arms |26 is flattened, or non-circular in shape, as clearly shown in Fig. 9 and it will be obvious, therefore, by rotating such rod by means of its handle or eye |45 that the end of the arms |26 will be lifted up, separating the corrugated roll |29 a sufficient distance from the corrugated roll ||4 to allow the strip of pap o be threaded therebetween. Formed intermediate the ends of the standard 90 is a bearing |33 in which is rotatably mounted a shaft |34, which shaft lies parallel to the shaft 92 above described. Secured to the end of the shaft |34 by setscrew |35 is a grooved pulley |36. Formed on the hub 28 of the driving pulley 21 is a pulley groove |31 that is in alinement with the groove in the pulley |36 and in the pulley grooves runs a belt |38 and by means of which rotary motion is imparted to the shaft |34 from the drive shaft 3. Screwing into the bearing |33 so as to engage the shaft |34 is a wing screw |39 for a purpose to be hereinafter described. The shaft |34 extends from the bearing |33 parallel to the shaft 92 and this extended portion is greater in diameter than the portion that passes through the bearing |33. This enlarged portion is provided with a longitudinally extending keyway or groove |40. Slidably mounted on the enlarged end of the shaft |34 are collars |4|. each provided with a threaded hole to receive a thumb screw |42l the end of which is guided into the keyway or groove |40. By properly adjusting the collars |4| on the enlarged end of the shaft 34. the strip of paper 98 is properly guided. as clearly shown, for example, in Fig. 3. Each of the collars |4| is provided with a hole, the holes being in alinement with each other and through which passes a rod |43, which rod is provided on its end with an eye |44 and by means of which the rod |43 may be handled or operated. The end of the strip of paper 98 is folded over about two inches from its end and placed under the rod |43. By revolving the shaft |34. the end of the paper 98 is started onto the shaft |34. After the paper has been used and Wound from the shaft 92 onto the shaft |34. it may be easily removed from the shaft 34 by withdrawing the rod |43. While placing the folded end of the strip of paper under the rod |43 and while adjustably securing the collars |4| in position, the wing setscrew |39 is utilized to hold the shaft |34 against rotation.

The operation of my improved apparatus is as follows, it being assumed that such apparatus is constructed as above described. An appropriate cutting anvil 81 having secured thereon a cutting die 15 in which is fashioned the particular design desired to be cut from the material is provided. It is assumed that the design on the die 15 is that shown in Figs. 16 and 17 or may be that shown in Fig. 11. A mask 19 is provided with an appropriate cut out 88 of such shape as to allow the seam or other ixed or nished part on the upper to be clearly viewed through such opening and the seam properly centered with respect to the design on the die. This mask 19, to hold, to guard, guide, and protect the work is attached to the cutting anvil 61 by the hinge 18. The stop block B3 is now positioned on the platen 25 in such manner that the die 15 attached to the cutting anvil 61 will be located beneath the plunger 2| when the base 66 is in its rearmost position and against the stop plate 20|, and resting on the supporting post 68 in balanced relation to the design of the die so that equal pressure will be placed on all parts of the die. A roll 93 of paper 98, such paper being of substantial thickness as compared to the thickness of the material being worked on, is placed on the shaft 92, drawn over and around the curved guide plate 96 and under the guide tension roll |94. the guides 91 secured in position, the paper passed over the curved guide plate |06 rearwardly oi' the machine between the corrugated rolls ||4 and |28. as above described, the end 0f the paper 98 folded and passed under the rod |43 and around the shaft |34. The horizontal plane in which is located the cutting edge of the die 15 is spaced apart from the horizontal plane in which lies the lower face of the facing 24 attached to the plunger 2| when such plunger is in its lowermost position. a distance less than the thickness of the strip of paper 98. The strip of paper 98 will, therepaper is presented to the dies at every stroke of the press, there is, in reality, a new die block brought into association with the die at every stroke of the press. Further, as the strip of paper 91 is never entirely cut through by the cutting die 15, the amount oi movement o1' the strip of paper for each stroke of the plunger of the press need only be suiiicient to present a new uncut has heretofore been the custom. It being assumed that the paper 98 is threaded through the' machine, the appropriate die and mask fitted on the cutting anvil 61, and the stop block 68 properly adjusted, power may now be thrown onto the machine through the pulley 21. The operator slides the base 66 back or to the right, as viewed in Fig. 1, throws the mask 19 into an upright position.' as viewed in Fig. l2. places an upper 8| into approximate position over the die 15. then swings the mask 19 downward so that the portions 82 and 83 thereof engage with the upper and, by grasping said upper on either side of the cutting anvil 61, the cutout portion 88 may be utilized as a means for registering and centering the seam or other finished part of the upper with respect to the design on the die 15 even though such die 15 is hidden from view by the upper and seam. After properly centering the upper 8|, the mask 19 is pulled down into the position shown in Fig. 13. The

to the engagement of the stop block 68 by the base 66, the cutting anvil 81 will engage with the arm on the shaft 62. Such shaft 82 will be shown) is able to pull down the treadle rod 46, rotating the member 45 about the shaft 38 and but to the left, 52 of the latch member plate 42 attached to the 49 engaging with the arm 35 will. move the l hook end 52 from the plate 42. Immediately such` to the shaft I3 which, by means of the eccentrics I4 and I5, will cause a downward movement of the plunger 2|, thus bringing the facing 24 on the bottom of such plunger against the paper 93 and forcing the paper 93 into engagement with the cutting die 15. The parts are now in the position shown in Fig. 14 and it will be noted that, while the cutting die 15 has penetrated the strip of paper 93; it has not pierced such paper which, to all outward appearances on one face thereof at least, is intact. 49 is moved outward, or to the left, as viewed in Fig. 7, the cam surface 53 on the lower edge thereof rides up on the upper end of the cam screw 55, causing a rotative movement oi' the latch member 49 about the pin 43 and over the hook end 32 is freed from the plate 42, the spring 43 forces the upper free end oi.' the arm 35 to the right, as viewed in Fig. '7, and moves the wedge-shaped member 34 in position to engage with the V slot 3 in the plate 32 in such plate which was brought into position by the rotative movement of the shaft I3. On engaging with the v slot 9, the wedge-shaped member 34 moves the plate 32 to the left, as viewed in Fig. 4, uncoupling the shaft I3 from the pulley 21. The upper end of the arm 35 engaging with the plate 32 positively stops further rotative movement of the shaft I3. This device is, therefore, a positive one revolution clutch, and but one revolution can be imparted to the shaft I3 by one operation of the treadle rod 46 which must, of necessity, be returned to its initial position in order to allow the hook end 52 and the member 49 to plate 42.

Rotativo movement of the shaft I3 causes, also, rotative movement of the face plate |24 and, therefore, a complete reciprocatory movement of the connecting rod |23 for each complete revolution of the shaft I3. Reciprocatory movement of the connecting rod imparts a reciprocatory movement to the arm IIG and the pawls |22 engaging with the ratchet wheel ||5, impart an intermittent rotary movement to the shaft IIB. The corrugated feed roll ||4 on the shaft ||3 and the corrugated feed roll |23 gripping the paper 93 therebetween, impart a feeding movement to the left, as viewed in Fig. 1, to such paper. As the slight length of paper 93 is fed to the left, as viewed in Fig. l, by the feed rolls ||4 and |23, which creates a slackness in that length of paper extending from the corrugated rolls to the shaft |34. The belt |33 is rather slack on the pulley |33 and in the pulley groove |31, so slack, in fact, that there is a slippage between the belt |33 and the pulleys so that the shaft |34 constantly tends to pull the strip of paper 93 from the feed rolls |23 and ||4. As soon as such slack is created in the length of paper 93 from the feed rolls to the shaft |34, the belt |33 will rotate the shaft |34 sufficient to take up such slack.

The sequence of operations above described may take place indefinitely, the paper 93 being moved step by step across the path of the plunger 2| to present a new uncut surface to the die 15 and the extent of each step by step movement is sumcient for this purpose and is short enough to insure that practically every available bit of paper is used.

While I have necessarily shown and described the preferred embodiment of my invention somewhat in detail. it is to be understood that I may vary the size, shape. and arrangement of parts As the latch member within wide limits'without departing from the spirit of the invention.

Various modifications within the scope of the invention and the appended claims will readily occur to those skilled in the art. Thus I may reverse the position of the cutters and mount the same on the movable plunger or other pressure applying means; the plunger may be moved either from above downwardly, or from below upwardly; the entire cutting anvil, while preferably in a vsingle unit, including the cutting instrumentalities, stripper plates, cutting and guiding masks, may, of course, be separated into co-operating or interchangeably locked parts. Also while it is an important feature of the present machine to utilize relatively heavy paper through which to perform the cutting action, it is, of course, entirely feasible to employ a soft material, such even as a sheet of brass, composition, rubber or the like suitable cutting surface. Paper is preferred because it does not dull the cutting edges of the die. It will also be appreciated that my machine in addition to the capacity for performing the highly ditlicult and involved cutting out actions on closed shoe uppers, as herein illustrated and explained, is also capable of performing the more simple cutting out actions, such for example as tip perforating, toe' ornamentation, etc., and in fact the cutting devices could be fitted to perform both cutting out and tip perforating simultaneously, ,as will be readily understood. By means of the construction and arrangement of the cutting anvil and the clearance or space allowing for concealing, protecting and guarding the shoe upper at any `point below the plane of the cutting operation by recesses in the top, at the side or underneath the anvil, a substantially universal cutting, perforating, and ornamenting machine, particularly suitable for advantageous use in shoe manufacture, is produced, giving a machine of this type suitable for performing all these intricate operations on shoe uppers or parts of the same, which heretofore required separate machines or difllcult hand operations. The feature of my work support which is capable of use both in operating upon flat or sheet material, the

combination of materials such as is presented in a shoe upper of joined parts, lining, etc., wherein clearance and space is provided around and about the support, preferably below the line of the cutting operation, is of the greatest importance. Particularly is this feature important when operating upon a shoe upper, whether at, a fitted or partly fitted upper, or a completely fitted and closed upper. That part of the work which is not being operated upon to constitute the cutout portion, may thus be protected, guarded and held within the recesses, spaces, clearance or room about, under, or partly under the work support, which capacity is one of the important characteristic novelties of my present invention. This feature of the protecting recesses, space and clearance, distinguishes my present` invention fromall former tip perforating or the like machines, wherein a nat bed or support was utilized, but without any capacity for operating upon any work except flat pieces. As above noted, my machine will do all the operations heretofore performed upon flat bed machines, and in addition thereto, will operate advantageously upon articles having a curved contour such asis presented in shoe uppers. For this latter work I may apply a tted, partly fitted, or completely fitted and closed upper on the work support, positioned either as shown in the drawings or in reverse directiomand indeed may position the work supporting slide either shown or in reverse position.
